3D movies are a great invention because they let people who are watching them experience and get more of these films that a regular 2D movie. But there is whole bunch of technology including cameras to capture any movie in 3D that is very interesting and exciting.

The 3D cameras essentially are two or more cameras rigged together to capture the movie from different angles at the same speed in a way similarly to how human brau captures real world.

Some 3D cameras also have dual lenses that are 3 inches apart. That is done to make the camera similar to human eye. Each of our eyes perceive image in a bit different way and our eyes are roughly 3 inches apart so by mimicking the human eyes with the camera lenses the movie makers are able to capture similar picture with depth as our eyes do. later by using the 3D glasses we alternate the image so that our brain can process it and make an illusion that the movie we are seeing have depth.

To shoot close up shots in 3D the two cameras or two lenses have to be placed very close to each other to get the right depth. So here cameramen use mirror rings – two cameras that are operated from the same lens, but the image is split the way it needs to be for 3D movie by two very little mirrors, hence the name mirror rigs.

Because it is pretty impossible to capture image with the ideal 3D depth perception so the filmmakers, producers and screenwriters all need to work together and write the screenplays that have shots that are suited to 3D cameras. They usually are usually shots that triangulate geometric distance, so that the screens look good on 3D screens. That is why careful and perfect shot planning will not only make the film director job easier but the shooting will be easier too and the film might end up looking much better.

After all the scenes are shot there is special software that is used to edit the footage into movie. This software lets the editors match the image up in the correct relation with geometric algorithms so that that the movie appear in 3D, as well as edit the rest of the film. This software is also a big part of 3D movies, because without the software you wouldn’t be able put together the footage that was filmed with the 3D cameras.

So there you have it – how 3D cameras work and in addition also what helps the 3D cameras to create the ideal 3D movie.
